After a point you will have added all the notes available i.e 7 notes as there are only 7 notes in the Major Scale:

1 - 3 - 5 - 7 - 9 - 11 - 13

From this point onwards the chord naming gets a bit messy so you just have to practise it, I could delve deeper but it would be a long read and you would fall asleep.

Caution on language: some people say Natural 7 while others say Major 7. For me, Major 7, is more common but natural 7 is more appropriate. You have to learn to read between the lines sometimes of what is written.
